KNITTING MACHINE.

Application filed December 9, 1922. Serial No. 605,755. i

cam ring being the rotating elements. The

object ofmy invention isto provide means for locking together thecylinder and dial without employment of the usual dogs on the inner'faceof the cylinder and the under falce of the dial, an object which Iattain in the manner hereinafter set forth, reference being had totheaccompanying drawings, in

Whichv g Fig'. 1 is a view, partly in side elevation of a circularknitting illustrate my invention, Fig. 2 is a Vtransverse sectional viewon the line 2 2, Fig. 1, and e Figs. 3 and 4 are views similar to aportion of Fig. 2 but illustrating certain modi# iications ofv myinvention.

Referring, in thefirst instance, to Fig. 1 of the drawings, thereisillustrated a portion of the fixed base 1 of a knitting machine towhich is secured a .non-rotating needle cylinder 3. Cooperativelypositioned, in respect to this cylinder, is a.y non-rotating needle dial4 mounted upon a central spindle 5 depending from an arch 6 which iscarried by posts 7 secured to, and upwardly projecting from, a ring 8 towhich movement of rotation is imparted by lmechanism common to this typeof knitting machine.

Secured to the vring 8 is a cylinder cam ring 9 provided with cams 10adapted'to operate the cylinder needles, the latter, for purposes ofclarity, being omitted from the showing. Y

Above the needle dial 4, and rotatably mounted upon the spindle 5 is adial cam ring 11 provided with cams 12 adapted to operate the dialneedles. These needles, also, are omitted from the showing.

In order to insure proper co-rotation of the cylinder anddial cam rings9 and 11, the latter is connected with the arch 6 in any suitablemanner, as, for instance, by means of a post 13 secured, at its base, tothe dial cam ring and having its upper end in engagement with the arch.

machine to properly In order to provide for the properlim-V mobility ofthe central spindle 5, while allowing necessary rotation thereabout ofits supporting arch and the dial cam ring, the` mechanism constitutingthe subject matter vertical section, of sufiicient.

vkeyed or splined a of my present invention is provided and will now' bedescribed.

Secured to the upper face of the spindle i engaging hub of the arch 6,and rotatable therewith, is a disk 14, rotatable within a ring 15 formedupon an arm 16 adjustably engaged with lan ed, in any suitablel manner,upon anyavailable portion of the base 1 of the machine FFICE. l

upstanding post l17 mount-y i or upon any portion of the -ixed fra-me ythereof. Other ,methods of' l mounting the'ring 15 and its armA 16 willreadily suggest themselves 'to` the skilled knitter and need ynot bedwelt upon, here.

kadj ustably Secured to the spindle .5, abovethe disk 14, is a collar 18upon whichis :vertically disk 19 provided withV a pair of notches 20 andv20a (see Fig. 2) adapted for the receptionof a corresponding pair ofbolt like terminals 21 and.21a of an oscillatory member 22 pivotallymounted upon the arm 16. An outside bearing may be provided for themember 22 by making its periphery circular and by providing theupstanding portion 15?L ofthe ring 15 with a corresponding Secured to,and rotatable with, the disk 14 is a cam 23 adapted to act, in turn,upon the bolts 21 and 21L of the member 22.

Piercing the cam yarn feed aperture 24 through which the yarnA passes onits way to the yarn guide 25, as shown in Fig. 1.V Y u In operation,as-the disk 14 and cam-23 rotate, the cam acts lirst upon'the bolt21,pushing it back outof the notch 20 tothe position shown in F' 2,therebyl permittingI theyarn to be carriedgbetweenthe outer falce of thedisk 19 and the end of the bolt. At the same time this is segmentalbearing portion 15b.v

23 andl the-,disk 14 `is aV being effected, the os! cillation of themember 22 causes the inser.` l

tion ofthe bolt 21a into the notch 20a. is vthis engagement ofthe disk19 bythe member 22, through the medium of its bolt, which insures thenecessary immobility of the central spindle 5.

Further rotation of 23 brings 21a and pushes it back out of engagementwith the notch 2O'al and clear of the path of the yarn. At thisreversely oscillated va the notch 20. Y

The length of the bolts 21 and 21a' and nd the bolt 21 enters Itv .timethe membervv22 isv the disk 14 and vcam l the cam into contact with thebolty ilo their degree of movement is such that the Kentering bolt isalways inengagement with its notch in the disk 19 before the departing,`bolt is free from its notch, so that, at no time, is the disk free fromengagement by one or the other of the bolts of the member 22. Anyaccidental movement of the central spindle is thus rendered impossible.

By making the cam 23 double ended, as shown in Fig. 2, its rotation maybe in either direction, or it may reciprocate, with equal facility.

Inv that, modiiication ot my invention shown in Fig. 3 the pivotalmounting fea- 'readily be-effected Without departure from thereof and itis to be.
